The song "My Darling Clementine" has been running through my brain since watching the classic John Ford film of the same name again this weekend. So much so that I've been trying to recall all the times I've felt this song made a difference in movies. That's what led me to watch 1963's "Hud" this weekend, too. There's a great scene in which the audience in a small-town Texas theater sings "Clementine" along with the bouncing ball. If knowing about the bouncing ball made me feel slightly old, the feeling was complete when I began reflecting on the use of a transistor radio in "Hud." In many ways, the film represents the fading of the Old West and the opening scenes of Brandon De Wilde walking through the early morning streets with a transistor radio in his pocket really drove this home for me. Transistor radios themselves -- at least in that form factor -- are themselves collectible history now.
